75rwkw was the official figure on mine

that was with 10psi from less than 3000rpm

through a 1.75" exhuast

and running out of fuel at 4000rpm (later found leaky fuel reg)

with some inlet air leaks



since then fuel pressure is up, exhaust is mandrel 2.5" and hopefully now i have found all the air leaks

unfortunately with someone rear ending the old shell (one week after new exhuast) and the fact that i've killed a set of rings running 16psi just recently... i've only driven it for one week it in the last 6 months

i'd love to dyno mine again properly but im still playing with things, and a proper tune up will be $900

project put another block in (a14 this time) starts this weekend, then hopefully i'll build a 15psi capable a15 block on the side

mad bonnet scoops are good, do that anyway!

cool air goes into hot turbo charger ----> hot air comes out and goes into motor.

Need to cool down the pressurised air in the pipe coming out of the turbo before it gets into the motor.

Hi dog160,

cold air induction is a good thing. Won't help the heat soak one little bit I'm afraid.

At any rate the power added will be lots of extra fun.

Rev 210, I know the suck thru set up isn't the best, but it is where I have to start. When this motor dies, then I will build an injected weapon!! We are going to mount the carby in behind the left hand headlight with a cold air box to try and negate the heat soak issue.

come on guys i wanted to see a15 power figure in here!!!

headworx @ Gold coast Qld have done well with a little a12...

it has a home made fuel injection setup with microtech and a gt28r ..
12psi made a datto gearbox breaking 190hp at the treads... on a conserative tune..

it now has a celica gearbox conversion with a crazy four puck clutch, full engine balance and a better flowing exhaust manifold... in the next month or so ill get u some better figures...

So far the a-series competitior the toyota 5k has made 156rwkws with 23psi and a to28.
I hope someone with an A cant match or outdo this figure reliably as that little 5k.

Hmmm... sounds like I may have to look closer at the Z18T I have at the back of the garage
Now Benny, you know not to tease the dog ........
It will only result in more work for me
Cheers

dog160,

An intercooler and fuel injection setup would be the very best thing to do for yours. Being able to apply 3D tuning to the motor will extract the very best out of the A series under boost.

Draw through is fine for the drags but, on a circuit intake temps are going to go through the roof and kill off alot of the power. You will find the first dyno run makes nice power but subsequent runs will be lower each time as heat builds. On the track it just gets worse.

Consider water/methanol injection kit if you are stuck with the carby setup to take the edge off the intake temps.

once i get mine wired up and dyno'd ill let you all know what hp mine makes should be pretty good, i just had my engine put in at jts yesterday, stainless steel valves, steel headgasket, low comp pistons, arp head stud kit, everything....
